Outdoor haze pollution continues to increase, so most people will not ventilate indoors frequently, but it will make indoor decoration pollution more and more serious. Formaldehyde detection has become a hot topic. How do people know the accuracy of formaldehyde detection?

　　如何保證甲醛檢測的準(zhǔn)確性?

　　How to ensure the accuracy of formaldehyde detection?

　　1. 甲醛檢測儀器的基本原理:基于有機(jī)化學(xué)基本原理的甲醛檢測儀器相對客觀、準(zhǔn)確，電子設(shè)備的感應(yīng)受傳感技術(shù)的影響。

　　1. The basic principle of formaldehyde detection instrument: formaldehyde detection instrument based on the basic principle of organic chemistry is relatively objective and accurate, and the induction of electronic equipment is influenced by sensing technology.

　　2. 甲醛檢測環(huán)境:檢測室內(nèi)所有正常空氣質(zhì)量時，門窗應(yīng)關(guān)閉，家具柜、柜應(yīng)關(guān)閉。如窗戶關(guān)閉而家具柜打開，甲醛檢測結(jié)果均通過正常高的室內(nèi)空氣質(zhì)量。甲醛在培養(yǎng)基中的濃度。

　　2. Formaldehyde detection environment: When testing all normal indoor air quality, doors and windows should be closed, furniture cabinets and cabinets should be closed. If the window closes and the furniture cabinet opens, the formaldehyde test results pass the normal high indoor air quality. The concentration of formaldehyde in the medium.

　　3.甲醛檢測溫度:規(guī)范中沒有明確規(guī)定。只需要正常的自然環(huán)境(冬季16-24℃，夏季22-28℃)。當(dāng)溫度過低時，室內(nèi)甲醛蒸發(fā)會很低。

　　3. Temperature of formaldehyde detection: There is no explicit stipulation in the specification. It only needs normal natural environment (16-24 C in winter and 22-28 C in summer). When the temperature is too low, indoor formaldehyde evaporation will be very low.

　　4. 關(guān)閉時間:按《工業(yè)建設(shè)項目室內(nèi)空氣污染控制標(biāo)準(zhǔn)》GB?《50325-2007(2013年版)條例》規(guī)定裝修的甲醛濃度值不高于0.08m3，適用于房地產(chǎn)開發(fā)商環(huán)境污染工程建設(shè)新項目的自然環(huán)境。根據(jù)《室內(nèi)空氣污染規(guī)范》GB/ t18883-2002，規(guī)定關(guān)閉13小時，裝修甲醛濃度值不高于0.5m3。本規(guī)范是指《世界衛(wèi)生組織裝修甲醛濃度值測定標(biāo)準(zhǔn)》，是對居住小區(qū)居民身心健康的較低標(biāo)準(zhǔn)。封閉13小時會使室內(nèi)空氣質(zhì)量中的甲醛濃度超過穩(wěn)定的平衡，即室內(nèi)空氣質(zhì)量中甲醛的飽和，無法在1小時內(nèi)準(zhǔn)確測量服裝、食品和交通條件下室內(nèi)甲醛的濃度值。

　　4. Closing time: According to "Standards for Indoor Air Pollution Control of Industrial Construction Projects" GB? Regulations 50325-2007 (2013 edition) stipulate that the formaldehyde concentration value of decoration is not higher than 0.08m3, which is suitable for the natural environment of new projects of environmental pollution construction of real estate developers. According to GB/t18883-2002, the concentration of formaldehyde in decoration should not be higher than 0.5m3 after 13 hours'closure. This code refers to the World Health Organization Standard for Determining the Concentration of Formaldehyde in Decoration, which is a lower standard for the physical and mental health of residents in residential areas. Closed for 13 hours will make the concentration of formaldehyde in indoor air quality exceed the stable balance, that is, the saturation of formaldehyde in indoor air quality, which can not accurately measure the concentration of indoor formaldehyde in clothing, food and traffic conditions in an hour.
